The 'Google Maps Address Manager' allows its users to position a marker on a map or just enter their address in some text fields, generating a map based on the supplied details.

'Google Maps Address Manager' is very useful because it uses a beautiful crafted interface for acquiring user locations and displaying them on a map automatically, saving data for later usage in a JSON file.

This app works as a stand-alone, but it will be more useful when integrated with more complex apps, like CMSs, store locators, online shops, task organizers, etc..
